This 3M Petrifilm Yeast and Mold Count Plate is a sample-ready-culture medium system which contains nutrients supplmented with antibiotics, a cold-water-soluble gelling agent, and an indicator that facilitates yeast and mold enumeration.

Yeasts are easily differentiated from molds on the plate:
Yeasts are typically indicated by small, blue green colonies with defined edges and no foci.
Molds are indicated by large, variably colored colonies with diffuse edges and center foci.
